# Overview - Billing Reports

The system generates four billing reports. Each report provides the charges for individual mailboxes by statistic, then calculates the total amount due. Each report serves a different purpose.

- Billing Reports are the standard reports, usually run monthly.

- Mailbox Blocked Reports (Blocked Billing Reports) retain a special format and are usually sent out to other databases via the serial port.

- Previous Billing Reports are run when a copy of the Billing Report from the last billing cycle is desired, or when a problem occurs during the "Gather" step of the billing procedure.

- Termination Reports are run when a mailbox is checked out and deleted, or when paging service is discontinued during a billing cycle.

This section outlines the steps involved to generate a Billing Report and provides instructions for running reports.
